Abstract

A high-pressure mercury lamp is provided that includes a transparent envelope (6) made of quartz glass, in which mercury, halogen, and a rare gas are sealed and a pair of electrodes (7) provided in the transparent envelope. The amount of the halogen sealed in the transparent envelope is in the range from 1.0 × 10-6 µmol/mm3 to 1.0 × 10-2 µmol/mm3, and 2.5 mol% to 25 mol% of oxygen with respect to the amount of the halogen is present in the transparent envelope. The high-pressure mercury lamp can prevent blackening of an inner wall of the transparent envelope from occurring over a long period of lighting without deteriorating the startability or lamp characteristics, thus achieving a long life.
